The multiple factor performance of multi-address protocol was analyzed and applied it in the Web communica-tion. An improved QoS asynchronous prediction algorithm was proposed based on the multi-factor and multi address proto-col. The QoS prediction algorithm was researched, Web communication channel modeling was constructed, which including congestion control, error control design. The frame rate and bit rate adaptive control was realized as result. Simulation re-sults show that the new algorithm can overcome the weakness of traditional method that the packet loss rate increases with the total output rate, and the algorithm can meet the demand of large scale Web resource communication. It has perfor-mance such as superiority and universality with good convergence. Research result has good application prospect in a stor-age cyber source transmission communication.
